My wife has just suggested that these small wooden mushrooms would make good accents. We buy them from a local wood turner who comes to our church's annual Craft Fair. Prices range from around £2 - £7, depending on size and wood used.

If anyone is interested, please let me know and I'll see if he'll let me have some 'on approval'.

Thanks Will, I'd forgotten about that article. Not long after that, I started incorporating fungi, including the scarlet wax cap, alongside some trees (in the pot rather than as an accent) and it worked very well. I guess the downside is their seasonality so perhaps the artificial ones could come into play then.

Peter Snart displayed his Cork Bark Oak along with a nice wooden mushroom accent. Here it is at an exhibition I ran at Glasgow Botanic Gardens.
